Procedure for Using FINS/TCP
FINS/TCP Method
1,2,3...
Note
Note
After a connection has been established as a FINS/TCP client, it can be termi-
nated in the following ways.
Even if the connection is closed at the FINS/TCP client, requests continue to
be made to the FINS/TCP server every few seconds to open a connection.
After the EtherNet/IP Unit or built-in EtherNet/IP port is powered up or
restarted, the IP address for the connection used as the FINS/TCP client is
the remote IP address that was set in the FINS/TCP Tab Page of the CX-Pro-
grammer’s Edit Parameters Dialog Box. To dynamically change the remote IP
address (i.e., during CPU Unit operation), execute the CMND(490) instruction
in the ladder program and send a FINS command (FINS/TCP CONNECTION
REMOTE NODE CHANGE REQUEST; command code: 27 30 hexadecimal)
to the EtherNet/IP Unit or built-in EtherNet/IP port.

• If there is no response from the client when the keep-alive function is in
effect.
